Answer:
False
Step-by-step explanation:
Angles a and b add to 180° (linear pair), so angle b is 68°.
Answer:
With all the lines, I may be wrong. But I'm confident that line B has a slope of 2.
This is because it rises up 2 up the y axis for every one unit on the x axis.
5/8 = .625
531.25 / .625 = 850
850 - 531.25 = $318.75
Answer:
75% off
Step-by-step explanation:
I would personally say use a calculator, but whatever your instructor says.
First, do $600 off. You could also do 75% off first, but you choose. If you subtract $600 from $868, you get $268.
Next, do 75% off. If you take 100% - 75%, you get 25%, or 1/4. Multiply $868 by 1/4 and you get $217, which is the better deal.
So, to conclude, $217 is less than $268, and therefore 75% off is the better deal.
Here is an example(i don't really know how to explain)
